X-Men: First Class Trailer

“Before mutants had revealed themselves to the world, and before Charles Xavier and Erik Lehnsherr took the names Professor X and Magneto, they were two young men discovering their powers for the first time. Not archenemies, they were instead at first the closest of friends, working together with other mutants (some familiar, some new), to prevent nuclear Armageddon. In the process, a grave rift between them opened, which began the eternal war between Magneto’s Brotherhood and Professor X’s X-Men.”

The film, which won’t be in theaters until June 3, 2011, is seen by Fox as both a prequel to the three primary X-Men films and as the beginning on a new trilogy.

X-Men: First Class is produced by Bryan Singer, directed by Matthew Vaughn and stars James McAvoy as the young Professor X; Michael Fassbender as Erik Lehnsherr, who becomes Magneto; Kevin Bacon as villain Sebastian Shaw; and January Jones as Emma Frost. Principal photography took place in London.
